Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86580, here are decompositions:
- 7 + 86573 = 86580
- 19 + 86561 = 86580
- 41 + 86539 = 86580
- 47 + 86533 = 86580
- 71 + 86509 = 86580
- 79 + 86501 = 86580
- 89 + 86491 = 86580
- 103 + 86477 = 86580
Showing the first eight; more decompositions exist.
